Apply Protective Sealer

What happens in this clip

Once the stain has thoroughly dried, a clear protective sealer is applied to the floor. The contractor recommends a semi-gloss finish for a balanced look, providing some shine without being high maintenance. A wide applicator, possibly a T-bar or lamb's wool applicator, is used to spread the sealer evenly across the floor. Multiple coats are typically applied, allowing adequate drying time between each coat, to build up durability and achieve the desired sheen.

Goal: Protect the hardwood floor with a durable, semi-gloss finish

Tools

• Wide Applicator (T-bar or Lamb's Wool)

About the full video

This project details the process of refinishing old hardwood floors, specifically focusing on the challenges of removing stubborn carpet adhesive, filling gaps and cracks between floorboards, and applying a stain and sealer for a revitalized look. It covers the stages from aggressive sanding to fill gaps with a custom mixture and finally staining and sealing the floor.

Step 4 of 5: Apply a Protective Coating or Sealant

For hard flooring materials like tile or sealed wood, apply a clear, durable floor sealant according to the manufacturer's instructions. This typically involves applying thin, even coats using a brush or roller. Allow adequate drying time between coats and before allowing foot traffic. Ensure good ventilation during application and drying.
